Portion of a container



FIG. 1 is a side elevation illustrating a portion of a container, in accordance with my new design, the sides not shown being mirror images thereof; and,

FIG. 2 is a top plan view thereof.

The broken line showing the neck and bottom portion of a container is for illustrative purposes only and forms no part of the claimed design. In addition, the broken lines which define the bounds of the claimed design also form no part thereof. 

The ornamental design for a "portion of a container", as shown and described.
